将混合类型的数据帧写入文件 Python Pandas

Question

I have a data frame which looks like this:

Col1, Col 2, Col3
'abc', (1,2), [(1,2), (3,4)]
'xyz', (3,4), [(1,2), (3,4), (5,6)]

I have written the data frame to file using df.to_csv("dataframe.csv")

When I read the dataframe by file = pd.read_csv("dataframe.csv") , I get Col2 and Col3 as strings. However, I would like to read Col2 as a tuple, and Col3 as a list of tuples.

How can I do that? Alternatively, is there another way that I should write the data frame to file, so that I can read the columns in the desired formats?

Answer 1

file = pd.read_csv("f500.csv", dtype = {"Col2": np.object, "Col3": np.object})
